Walk-on rooflight installation in Chippenham

Builders and extension firms in Chippenham often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a walk-on rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around SN15 and the neighbouring districts are welcome.

Fitting across Chippenham and nearby

If you also own a property or a business unit in Calne, Melksham or Devizes, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and SN15, SN14 and SN13 sit comfortably within that pattern.

What we check on a supplied unit

There are two ways to do this. Supply and fit means we source a walk-on rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What the job includes

  • Protective film removed and the anti-slip surface left clean
  • Lifting plan for the unit, including people or gear for the day
  • Unit bedded and fixed so it sits level with the finished surface
  • Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.
  • Weight on delivery day — We plan the delivery and lift before booking any lifting gear or extra hands.

How a fitting day runs

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a walk-on rooflight: one to two days, weather permitting.

Regulations for Chippenham properties

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

Before you get in touch

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SN15, and we can price it.

Common questions in Chippenham

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.

What upstand height and roof pitch does walk-on rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Do you cover Chippenham?

Yes. Fitters travel to addresses in Chippenham and the surrounding districts, including SN15. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

Got a unit waiting to go in, or need one sourced? Either way, start with your Chippenham address and a couple of photos.
